*The relative density D20/4is the ratio between the measured density of the test substance at 20°C and the density of water at 4°C (= 0.99997 g/cm3). The relative density has no dimension.
Check measurement: Density of degassed deionised water at 20°C: 0.99820 g/cm3
Reference value: 0.99820 + 0.00005 (20°C)
Description of key information
Relative density: 0.878 at 20°C (OECD 109)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.878
Additional information
A measured relative density value of 0.878 at 20°C was determined for the registered substance using an oscillating densimeter in accordance with OECD Test Guideline 109 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study. This value is supported by a predicted density value of 0.89 g/cm3 at 20°C using a validated QSAR estimation method.
In other secondary sources to which reliability could not be assigned, density values of 0.88 g/cm3 at 20°C and 0.876 g/cm3 at 25°C were reported for the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
